Main Battery Charging
The CK30 itself contains no battery charging circuit. Instead, the charging
circuitry resides in the charging accessory–the AC1 4-bay charger, or the
AD1, AD2, or AC2 dock. The battery may be charged either by itself (in
an AC1) or while installed in a CK30 (in an AD1, AD2, or AC2 dock).
